Added RapidFire power up and improved 3D level design

GitHub asked me to recommit everything in order to merge with the
preexsisting commits. I am very sorry if this messes up with anyone’s
progress.  I have also added a texture to the meteor.
Merge branch 'master' of https://github.com/zachgreer/deathperception
